Hi,
We have 5 sql servers located on VM's with 3 instances each. 2 of the sql's are on one physical host, and the other 3 are on another. (running hyperv)
Our storage is an equallogic SAN.
What is the better option:
1. Create one lun for data and one for log for each of the instances, meaning 15 luns for data and 15 for logs.
2. Create a large lun for data and a large for logs, and then create fixed virtual hard disks (one for log and one for data) and give them to each of the instances.
Which would perform better?
And a second question, is it ok to use dynamic disk for the VM itself? not the data/log luns, but for the operating system.
Thank you
